Glen, I'm experiencing a very similar problem, but I get a slightly
different entry in the log:
[04/03/2000 20:23:04:810] (INFO) wrapper: Java VM not responding
(PID=27237) [timeout]
[04/03/2000 20:23:05:820] (EMERGENCY) ajp12: auth did not receive
challenge size
[04/03/2000 20:23:05:820] (EMERGENCY) ajp12: function auth fail
[04/03/2000 20:23:05:820] (INFO) wrapper: Java VM restarting (PID=27237)
[04/03/2000 20:23:05:821] (INFO) wrapper: Java VM spawned (PID=27589,
PPID=27237)
Everything else, however, is identical. As far as I can tell, my servlet
is blocking while writing to the output stream (huge file, just like
yours) and when jserv tests itself, it auto-restarts. If I adjust the
ApJServVMTimeout value (default is 10 seconds, set in jserv.conf) it
stays alive appropriately. I don't think, however, I want to switch this
timeout off, as it should protect against real problems!
Who knows _why_ the JVM is not responding during downloads... it should
be nice & multi-threaded, right?!
Anyway, I'm scrounging for ideas... have you managed to work something
out at your end? I've been fighting this for two days, now... very
annoying!
Cheers,
-Simon
