[Asterisk-Users] Back-to-back connected boards load test
Hi Alex, About:> WARNING[12301]: File chan_zap.c, Line 5342 (zt_pri_error): PRI: Readon 203 failed: Unknown error 500 Similar warnings on my system are generated due to shared IRQ t1xxp and ide0 (/proc/interrupts). Just my 0.02$ Konrad -----Original Message----- From: asterisk-users-admin@lists.digium.com [mailto:asterisk-users-admin@lists.digium.com] On Behalf Of Alex Zarubin Sent: Thursday, July 17, 2003 2:31 AM To: 'asterisk-users@lists.digium.com' Subject: [Asterisk-Users] Back-to-back connected boards load test Hi, Two asterisk boards in two asterisk boxes are connected back-to-back with crossover cables. T400P (box1, pri_net) creates a flow of calls, TE410P (box2, pri_cpe) takes them. Cables are OK. Boxes are powerful. SMP is in place. Interrupts are distributed among CPUs. There are 2 TE410Ps in the box2. Spans 1-4 in box1 are connected to spans 5-8 in box2. The carrier T1 is in span 1 of box2 and provides clocking. All we want is to be able to have a consistent flow of 92 calls. All we can do is 75-80 calls. There are D-Channels downs and ups on the spans where new calls are sent. There are frame rejections and retransmissions. There are read failures on D-Channel fds with 'Unknown error 500'. There are PRI events 6 and 8 (HDLC-related). It gets worse as the total amount of calls goes up. The log (from asterisk start to the test finish is attached). Would greatly appreciate any advice on how to fight this. Thank you.
