Hi, I am running * with E100P board. At least every our I got an Error 500 message and ISDN-PRI restarts: Jan 10 12:53:02 WARNING[98311]: File chan_zap.c, Line 5758 (zt_pri_error): PRI: Read on 27 failed: Unknown error 500 Jan 10 12:54:27 WARNING[98311]: File chan_zap.c, Line 5758 (zt_pri_error): PRI: Read on 27 failed: Unknown error 500 Jan 10 13:33:01 WARNING[98311]: File chan_zap.c, Line 5758 (zt_pri_error): PRI: Read on 27 failed: Unknown error 500 Jan 10 13:33:48 WARNING[98311]: File chan_zap.c, Line 5758 (zt_pri_error): PRI: Read on 27 failed: Unknown error 500 Any clue?

I get lots of these in a very busy system, along with PRI frame errors/retransmissions. It is my understanding that this is due to an inadequate buffering mechanism in asterisk. Mark Spencer is aware of the problem, and has said he'll work on it soon. In small numbers, these can be safely ignored. Regards Scott M. Stingel Emerging Voice Technology Inc.

It is telling libpri that there is an event in the queue. If the read/write routines see that there is an event in the queue, it just returns ELAST. Libpri needs to do an ZT_GETEVENT to clear the event and should do some error handling if needed. -- Bob Knight [-w] the work option bk@minusw.com 925-449-9163
