Re: Can large upload cause tomcat hanging?
Just a suggestion, maybe you should have waited a little while for the commons-list to reply, since it is probable that people on the commons-list might have encountered the problem first.

RE: Can large upload cause tomcat hanging?
Sorry, if my cross-post disturbed anybody, but file upload is part of commons but that worked fine. I had problems with tomcat (and not with the upload) and it was (is) just an idea that this pretty large upload could be the reason why tomcat hangs. Martin, you wrote that uploaded files much larger than 70MB without any problems. What was your JVM settings? In my case tomcat-4.1.24 was running with -Xmx100M. Do you think that is too low?

First of all, do *not* cross-post your questions to multiple lists. I'm going to reply here and ignore your cross-post to commons-user. Why not? I've really never understood why people get upset about this. If the answer may be produced by an investigation or knowledge by Struts users, Tomcat users, or commons users, why not? The Struts users may be wholely ignorant of the underlying Tomcat file/IO restrictions, but the Struts/Commons upload mechanism is directly to bear on the problem. Please clear this up, if you would.

This includes the rule Do not cross post messages. Understood, but this is a Jakarta rule, not a standard Internet rule. The second URL you posted about smart questions states to not cross-post to too many different newsgroups. Too many is very different than an absolute never. Lastly, you must admit that I have a point to the previous statement about how an answer could only be answered across multiple forums. I've had very advanced questions in the past where the only solution was to cross-post. If not abused, it can be very helpful.
