Hi All, can someone please help in understand that how TCP connections are interlinked with the no. ofFile Descriptors & no of threads configured over a machine . Setup details :OD - Centos 6Tomcat7Java 7 Recently i have faced an problem in while my application was having +20k TCP connections in TIME-WAIT state resulting in choking my application though no consumed threads & Files descriptors are pretty less than threshold. 1) I would like to understand that is there any limit that how many TCP connections a machine can open , IF YES then how to tune it . 2) Second query , my understanding was every TCP connection will open one file descriptor but in my currentsituation only 900 FD were used whereas the TCP_WAIT connections where +20K .Kindly suggest how do i comprehend this . How these are interlinked 3) If i configure 600 threads in server.xml for my HTTP connector & if i'm running that machine over 8 core cpu does that mean simultaneously 600 X 8 (cpu core) =4800 threads will be served by my tomcat ?
