Hi,
I'm running JServ 1.1.1 with Apache 1.3.11 on WinNT 4.0 WKS with JDK 1.2.2.
My problem is, that I get sporadic thread dumps in the error-logfile. I
suppose this happens during
shutdown of Apache/JServ (JServ is running in automatic mode). I use the
default configuration for
Apache and JServ.
There are no entries in jserv.log or mod_jserv.log.
error.log:

(... stops here ...)
As one can see from the dump, no servlet was loaded before (access.log is
also empty).
Any help is appreciated ;-)
Ciao
