Hi
I have a problem when uploading files to tomcat through mod_jk. When
uploading smaller files (<100kb) everything seems to work fine, but
when uploading files of about 1.5Mb it seems as if the server is
restarting and causing a 503 error. I've tried modifying timeouts in
both apache and tomcat, still i get this output on the catalina.err
file: (sorry for long log files)

------
So I think its restarting the server for some reason. As far as I can
tell I'm not getting any errors on the startup of the server. Is
there any way to find out more about whats happening and maybe fix
this problem. My workers.conf is:
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
#
# Specifies the load balance factor when used with
# a load balancing worker.
# Note:
# ----> lbfactor must be > 0
# ----> Low lbfactor means less work done by the worker.
worker.ajp13.lbfactor=1
#
# Specify the size of the open connection pool.
#worker.ajp13.connection_pool_size
connection_pool_timeout=600
connectionTimeout=600000
#
The connector for the server is:
<Connector port="8009"
maxProcessors="50" enableLookups="false"
disableUploadTimeout="true" protocol="AJP/1.3"
connectionTimeout="180000" maxSavePostSize="-1" maxPostSize="0" />
I would post the rest of the file if its needed, but i think thats the
most important part.
The jk.conf from apache is:
JkWorkersFile /usr/local/jakarta/tomcat/conf/workers.properties
JkLogFile /usr/local/apache/logs/mod_jk.log
JkLogLevel info
JkWatchdogInterval 600
JkLogStampFormat "[%a %b %d %H:%M:%S %Y] "
JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
JkRequestLogFormat "%w %V %T"
I'm using tomcat 5.5, it would be difficult for me to upgrade. Can
anyone point out anything that I might be doing wrong, or if you need
any more info let me know
Thanks
