Tomcat3.3b1 crashes when rendering JPEGs

[Hans Schmid <Ha...@einsurance.de>]

Hi,

we have frequent crashes when rendering JPEGs:

Has anybody seen this kind of VM crash on Solaris 7?
We have to restart our Tomcat every 3-4 days because of this.

Our setup:

Apache 1.3.19, Tomcat 3.3b1, mod_jserv which comes with JServ 1.1.2 since we
still have our main part of the application running under JServ. Solaris 7

Question:
Are the sources in native/mod_jserv in the Tomcat 3.3b1 distribution
compatible with
JServ 1.1.2?
