Major Description
I have a java process that got stuck randomly while setting values into a pdf form with PDFBOX 2.0.24
the "strace" command return :
root@appname:/tmp# strace -p 26734 strace: Process 26734 attached futex(0x7f97791589d0, FUTEX_WAIT, 26735, NULL root@appname:/tmp# strace -p 26735 strace: Process 26735 attached write(2, "Aug 13, 2021 11:12:13 AM org.apa"..., 232
I added the jstack output of the process in the jstack.out attachment
Seem to happen completely randomly.
I don't have any issue if I rerun manually the same command.
