今天我的服务器由于流量的增大,开始出现了不稳定的情况,分有如下几种:
报错1:
2003-9-3 14:46:02 org.apache.jk.common.ChannelSocket processConnection
服务器: Error, processing connection
java.net.SocketException: Software caused connection abort: JVM_recv in socket input stream read

--不知道这是何原因导致,请教!!

报错2:
信息: server has been restarted or reset this connection
2003-9-3 15:04:18 org.apache.jk.common.ChannelSocket processConnection
--一出现此信息,网站基本上无法访问,或是速度极慢,不知道是何原因导致,请教!!

报错3:
2003-9-3 14:54:21 org.apache.tomcat.util.threads.ThreadPool logFull
服务器: All threads are busy, waiting. Please increase maxThreads or check the servlet status75 75
--这个我已经根据提示,我已把 ThreadsPerChild 设为300 ,现又改为了600 ,也不知能撑多久.


特此请教,各位高手!!! 急!!
