decided to go the ispconfig3 path. After install the server and some hickups I managed to get my server going smoothly. But now
Php Segfault Error 4
after 2 weeks my server is experiencing issues. All of a sudden my php-fpm segfault error 4 php sites cannot connect to the mysql database anymore and the following is displayed in the log files. I have to restart mysql to get it working again. I guess this means there is something wrong with my mysql but why do i receive php messages? because it cannot connect to mysql anymore? i guess it shouldn't segfault because of that right? I also looked for mysql errors but could not find any. Could this be a tuning issue, where php is requesting to many connections?

Yes, php does normally not segfault on connection problems. In most cases, segfaults are caused by hardware problems. You should check your server with e.g. memcheck. till, Jul 1, 2009 #2 marciliomcm New Member same my.. [ 48.371022] lp0: using parport0 (interrupt-driven).

December 20, 2015 1.4k views LEMP PHP Ubuntu A couple of https://www.howtoforge.com/community/threads/php-segfault.37139/ days ago, my OSSEC daemon started sending me syslogs about a segfault in my php5-fpm. Here's the portion of the logs: Dec 19 15:09:38 mydropplet kernel: [165740.998932] php5-fpm[26936]: segfault at 7fff621ad001 ip 000000000079fe74 sp 00007fff621a5040 error 6 in php5-fpm[400000+800000] So I peeked into my error logs to see if I had some PHP errors somewhere that were causing the segfault (since I am not sure what https://www.digitalocean.com/community/questions/how-do-you-fix-a-php5-fpm-kernel-segfault-error that even means, but sounds like it's something in the core) My error logs had this in it: 2015/12/19 01:36:49 [error] 6177#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 01:36:54 [error] 6177#0: gv.symcd.com could not be resolved (110: Operation timed out) while requesting certificate status, responder: gv.symcd.com 2015/12/19 02:00:06 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 02:00:11 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 02:00:16 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 02:00:21 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 02:00:26 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx 2015/12/19 02:00:31 [error] 6178#0: recv() failed (111: Connection refused) while resolving, resolver: xxx.xxx.xxx.xxx:xx So I took a closer look at my syslogs it had this in it: (segfault error) Dec 19 09:44:06 mydomain kernel: [146209.162601] php5-fpm[13787]: segfault at 7fff621ad001 ip 000000000079fe74 sp 00007fff621a5040 error 6 in php5-fpm[400000+800000] (the rest of it) Dec 19 09:44:59 mydomain postfix/anvil[26420]: statistics: max connection rate 1/60s for (smtp:195.22.126.137) at Dec 19 09:41:39 Dec 19 09:44:59 mydomain postfix/anvil[26420]: statistics: max connection count 1 for (smtp:195.22.126.137) at Dec 19 09:41

Initially there was some suhosin stuff in the backtrace, so I removed php5-suhosin from the system, but it still crashes. At this point I don't really know where to look next, since the stack seems 99% bogus: especially the apparent call to main(SHORT_MAX, NULL). Both old and new machines were/are 64-bit Lucid installs, up-to-date, using the standard debs (lucid-security & lucid-updates enabled). However, I already canceled the old server, unaware of this issue, so I can't double-check its logs. It's configured as: the internet -> lighttpd,mod_fastcgi -> php5-cgi = PHP 5.3.2-1ubuntu4.9 with Suhosin-Patch (cgi-fcgi) (built: May 3 2011 00:45:34). uname -a gives me: Code: 2.6.38-x86_64-linode17 #1 SMP Thu Apr 28 22:18:47 UTC 2011 x86_64 I tried searching the web, but all I've found so far are similar questions, without answers.
