And we tried a .docx to .pdf conversion again, but still its getting stuck with this log:
2026-01-07 08:07:37.120 INFO 448381 — [cTaskExecutor-1] o.m.c.a.util.AttachmentExportUtil : convertToPdfIfRequired :: Converting /C:/Users/suchitra.pv/attachments/AC_1767773256191/1_Service Request KDB.docx to PDF at C:/Users/suchitra.pv/attachments/AC_1767773256191/1_converted.pdf

The document I tried for conversion contained text in Arial font.

Could you please take look into these fonts and can we know if its enough?

22

Hello @suchithrapv ,

Yes, all fonts are installed correctly.

Does the hang you are describing occur with all documents you are trying to convert, or only with the specific file 1_Service Request KDB.docx?

Also, after installing the fonts, which version of our library are you using? Have you tried our latest version 25.12?

23

Hi @evgen.efimov

No, when we try conversion with any file, it gets hang and yes with installed fonts we’re using 25.12 version of groupdocs.

24

@suchithrapv ,

If you confirm that the hang occurs when converting all types of documents, then it can be safely assumed that this is not an issue with the library itself. Most likely, it is related to the environment or file paths.

I noticed in your logs that you are trying to convert a file using the following path:
/C:/Users/suchitra.pv/attachments/AC_1767773256191/1_Service Request KDB.docx

Please try adding a check in your code before starting the conversion to ensure that the path actually exists inside the container:

Path p = Paths.get(inputPath);
if (!Files.exists(p)) {
    throw new IllegalStateException("Input file does not exist: " + p);
}

Additionally, to verify that GroupDocs.Conversion can perform conversions without hanging, please try running our GitHub demo examples on a Linux system. If the hang does not reproduce there, it would indicate that the issue is not related to the conversion process itself.

Hi,

After our last conversation, we tried running a sample Java program of docx to pdf conversion in our Dev Environment with below spec:
NAME=“Red Hat Enterprise Linux Server”
VERSION=“7.9 (Maipo)”
ID=“rhel”
ID_LIKE=“fedora”
VARIANT=“Server”
VARIANT_ID=“server”
VERSION_ID=“7.9”
PRETTY_NAME=“Red Hat Enterprise Linux”
ANSI_COLOR=“0;31”
CPE_NAME=“cpe:/o:redhat:enterprise_linux:7.9:GA:server”
HOME_URL="https://www.redhat.com/"
BUG_REPORT_URL="https://bugzilla.redhat.com/"

REDHAT_BUGZILLA_PRODUCT=“Red Hat Enterprise Linux 7”
REDHAT_BUGZILLA_PRODUCT_VERSION=7.9
REDHAT_SUPPORT_PRODUCT=“Red Hat Enterprise Linux”
REDHAT_SUPPORT_PRODUCT_VERSION=“7.9”

and the conversion got successful, and we deployed our application too in Dev, there too the conversion got successful.

We deployed the same to QA environment with below spec:
NAME=“Red Hat Enterprise Linux Server”
VERSION=“7.9 (Maipo)”
ID=“rhel”
ID_LIKE=“fedora”
VARIANT=“Server”
VARIANT_ID=“server”
VERSION_ID=“7.9”
PRETTY_NAME=“Red Hat Enterprise Linux”
ANSI_COLOR=“0;31”
CPE_NAME=“cpe:/o:redhat:enterprise_linux:7.9:GA:server”
HOME_URL="https://www.redhat.com/"

REDHAT_BUGZILLA_PRODUCT=“Red Hat Enterprise Linux 7”
REDHAT_BUGZILLA_PRODUCT_VERSION=7.9
REDHAT_SUPPORT_PRODUCT=“Red Hat Enterprise Linux”
REDHAT_SUPPORT_PRODUCT_VERSION=“7.9”

but, here we got that conversion stuck issue with a basic .docx file (attached)
Document (1).docx (11.3 KB)

to .pdf conversion, and while checking the fonts in QA, we got the below data:

but, here earlier when we checked, we were not having /usr/share/X11/fonts/, which was existing in Dev, and we tried installing the same to QA, but still the issue exists.

Can we have a check on this issue asap, as we’re nearing to our release and we’re getting this issue in multiple envs.

Hello @suchithrapv ,

If I understood correctly, when you run your application in two development environments, the conversion works without issues, and the hanging occurs only when the application is deployed to the QA environment.

From the environment specifications you provided, both Dev and QA appear to be identical. However, could you please confirm whether the Java version and heap space settings in the Dev environment are exactly the same as in the QA environment?

Also, in the list of fonts you shared, I did not see the Microsoft fonts directory (/usr/share/fonts/msttcore/...), which was present in your previous response.

Please double-check on the QA environment whether fontconfig can detect Microsoft fonts by running the following commands:

fc-match "Arial"
fc-match "Times New Roman"
fc-match "Calibri"

I’ll be waiting for your feedback.
