Hi - I'm running mod_jk with an Apache front-end, and I'm having an
issue with the JkShmFile files.
Every time Apache restarts mod_jk creates two new files
(jk-runtime-status.PID and jk-runtime-status.PID.lock). These are never
cleaned up; the log directory simply fills up with these files. This
happens whether or not I explicitly set JkShmFile in the Apache conf.
That should no happen. There is a cleanup routine registered, which
should delete the files during shutdown. And that's the behavior that I
normally observe.
Is there some way I can persuade mod_jk to use a single file pair,
without the PID suffix, or to delete the previous file pair on a
restart? I'm not doing any load sharing.
If you must remove the PID, you can patch the code and build it
yourself. The ID is added in file common/jk_shm.c in the following line:
sprintf(jk_shmem.filename, "%s.%" JK_PID_T_FMT, fname, getpid());
You could replace it by:
sprintf(jk_shmem.filename, "%s", fname);
If you compile the code yourself, please us the latest version 1.2.49.
As I mentioned, a normal shutdown should already remove the files. A
reload should not change the pid and thereby the files. A restart in the
sense of stop-then-start should also remove the old files.
I'm on Ubuntu 22.04, Apache 2.4.52. The mod_jk version is possibly
1.2.48-1.
Thanks.
Regards,
Rainer
