how many traffic does have your site? it could be that you're having lots of hits that's just fine with me :-D Also, check the connection time out, maybe you have lots of connections lingering on your server. also, check if its from a set of IPs or just one IP that's hitting you *could* be an attack (unlikely, but could be) Randy Paries escribió: Hello all, I have this problem that I am looking for any kind of help I am not sure what is causing it, I just know how It shows itself A couple of logistical things RH9 jakarta-tomcat-5.0.24 Apache 2 So here is the problem.

RE: Help with a real ugly one
how many traffic does have your site? it could be that you're having lots of hits LOTS!! But the usage pattern is much more linear Also, check the connection time out, maybe you have lots of connections lingering on your server. Do you JNDI connection time out or connector timeout? also, check if its from a set of IPs or just one IP that's hitting you *could* be an attack I have had these before, but can usually spot them in the log files. But no this is not the problem either Thanks Randy Randy Paries escribió: Hello all, I have this problem that I am looking for any kind of help I am not sure what is causing it, I just know how It shows itself A couple of logistical things RH9 jakarta-tomcat-5.0.24 Apache 2 So here is the problem.

Also, check the connection time out, maybe you have lots of connections lingering on your server. Do you JNDI connection time out or connector timeout? Every connection timeout counts specially the TCP connection timeout someone recently posted a problem having lots of connections in TIME_WAIT mode could be your problem too - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Help with a real ugly one
Subject wrong... sorry another fact that really matters is your hardware specially if what you say about you traffic is true. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
