Re: TCP TIME_WAIT strange problem ( LINUX mysql 3.23.49 )
Hi, TIME_WAIT said to you that are still packet in the network which are unhandled after socket it's closed. The question is: ... why happend this? IFCONFIG show you information about network interfaces which is mounted in your computer and not about entire network.

Hi, What is written in err.log (/var/lib/mysql) ? I think you have some problems with network (switch or hub).

The problem occurs time to time ( during peac or idle time ). In fact mysql seem not to answer all connections. Netstat show several connections TIME_WAIT and show process_list only show 1 ou 2 queries running ... But on other way, 80% of the time, mysql works and answers well. At those moments netstat show lots of ETABLISHED; All connections are made through TCP/IP on a private LAN ( ip like 192.168.x.xx ). Server don't have access to internet. ifconfig show me that me eth0 config is clear : UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:17728939 errors:0 dropped:0 overruns:0 frame:0 TX packets:10940614 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 lg file transmission:100 RX bytes:1689574777 (1611.3 Mb) TX bytes:347460048 (331.3 Mb) Here is the config : uname -a Linux 2.4.7-10smp #1 SMP Thu Sep 6 17:09:31 EDT 2001 i686 unknown Red Hat 7.2 2 * 1Ghz Intel 1 Go of ram 2 Go of swap Raid 5 scsi hdds Running mysql 3.23.49 from mysql team tar.gz binary.

Is that an hardware problem ? Why not but the server isn't old ( only 3 mounths ). Linux ? Have a second mysq server with same hardware, same linux and same mysql and this one don't have any problem.
