What does "ps axlHp 798" print?  That will print the all the threads
plus what they are doing in the kernel.  There were some deadlock fixes
that went into libpthread after 5.3 was released.  Until 5.4 is
released, you can drop back to libc_r threading with this entry in
/etc/libmap.conf.  It shouldn't hurt spamass-milter's performance since
it doesn't really use much CPU anyhow.

You can use the "gcore" command to generate a coredump from a running
process. Handy in situations like this.
