RE: Listener -thread error -27001

I have a similar error. listener-thread: err = -25573: oserr = 72: errstr = : Network driver cannot accept a connection on the port. System error = 72. It's on a dual CPU box running AIX. One processor will sit at 100% Usr utilization while the other sits at 0. Sometimes it will clear itself up other times the only solution is to hit the power button. *yikes* I have increased NETTYPE soctcp,2,1000,CPU per IBM's recommendations but no fix. IBM says upgrade to 9x AIX says to upgrade the OS. Both are cop out excuses and don't explain why the problem happens. -----Original Message----- From: Mukanyi Tariro [mailto:Tariro.Mukanyi@icl.co.zw] Sent: Tuesday, August 05, 2003 11:00 AM To: 'Michael Mueller' Cc: informix-list@iiug.org Subject: RE: Listener -thread error -27001 Thanx I'll try that! -----Original Message----- From: Michael Mueller [mailto:michael.mueller01@kay-mueller.de] Sent: Tuesday, August 05, 2003 4:51 PM To: Mukanyi Tariro Cc: informix-list@iiug.org Subject: Re: Listener -thread error -27001 Try reducing INFORMIXCONTIME to just a few seconds (set on the client side!). Set it as low as you can. You can use onstat -g ath to see how long the soctcplst thread will be sleeping. During this time nobody else will be able to connect: Threads: tid tcb rstcb prty status vp-class name 12 1093d4e0 0 3 sleeping secs: 9 1cpu soctcplst Maybe you also can find out why it happens so often. What kind of clients do you have? This is normally caused by a client machine that crashes (often a PC) before the initial packages between the client and the server are exchanged or by a hanging network connection.
