Previous Comments: ------------------------------------------------------------------------ [2007-09-20 12:41:46] mamatkazin at ivc dot orw dot ru Sorry for my English. program is a big and uses several external pear classes. This generates a monthly report of our company. there are several large sql queries to DB2 on zSeries. my colleagues programmers could not seriously reduce it. I can put it as is. after several attempts run problem script, php hangs. I press Ctrl-C and saw: Starting program: /usr/local/php5-fcgi/bin/php-cgi -b 127.0.0.1:1026 [Thread debugging using libthread_db enabled] [New Thread -1217100096 (LWP 13395)] Program received signal SIGINT, Interrupt.

To properly diagnose the problem, we need a short but complete example script to be able to reproduce this bug ourselves. A proper reproducing script starts with <?php and ends with ?>, is max. 10-20 lines long and does not require any external resources such as databases, etc. If the script requires a database to demonstrate the issue, please make sure it creates all necessary tables, stored procedures etc. Please avoid embedding huge scripts into the report. We really need a reproducible script for this... ------------------------------------------------------------------------ [2007-09-18 07:10:20] mamatkazin at ivc dot orw dot ru Description: ------------ I got this error on some BIG script and can't reproduce it on small example. This error happens nearly 1 from 5-10 request to this script. This GDB was configured as "i486-slackware-linux"...Using host libthread_db libr ary "/lib/tls/libthread_db.so.1".
