I only happens when I add a new Inputfield module (not happens with other types!) if the error wouldn't be strangely enough already added Inputfield module seem to work. I found some infos out there but all seem not to be related and it seems like a apache/php/hardware problem. I'm lost from apache error_log: [Fri Jul 26 https://processwire.com/talk/topic/4133-child-pid-exit-signal-bus-error-10/ 14:51:29 2013] [notice] child pid 584 exit signal Bus error (10) [Fri Jul 26 14:51:30 2013] [notice] child pid 525 exit signal Bus error (10) [Fri Jul 26 14:51:30 2013] [notice] child pid 524 exit signal Bus error (10) [Fri Jul 26 14:52:31 2013] [notice] child pid 586 exit signal Bus error (10) [Fri Jul 26 14:55:19 2013] [notice] child pid 630 exit signal Bus error (10) [Fri Jul 26 14:55:52 2013] [notice] child pid 523 exit signal Bus error (10) [Fri Jul 26 14:57:36 2013] [notice] child pid 589 exit signal Bus error (10) [Fri Jul 26 15:02:19 2013] [notice] child pid 3120 exit signal Bus error (10) I first thought it's a syntax error or something but after hour of trying it's all right and when I try to create a test Inputfield it happens again.

Fixes include: restart Apache reseat memory (if you have access) Share this post Link to post Share on other sites Soma 5,958 Dreamer Moderators 5,958 6,479 posts LocationSH, Switzerland Posted July 26, 2013 · Report post Thanks but that's a common routine check, already tried "everything" possible (usual tasks).

What I have is php 4.4.6 and APC 3.0.13, running under Apache 1.3.37. I took a sample of all unique GET URLs of my live site and replayed them on the test server, bus error so the test is not run in a high load environment. Nevertheless, sooner or later during the replay, apache childs crash with : [notice] child pid 30366 exit signal Bus error (7) As long as the APC console is working, it does not show any problem; no fragmentation and the memory usage is not more than 50% of the 64 exit signal bus MB I assigned to APC. After the errors occur, the server is unstable. Static files can be served, but the APC console (and most - but not all- other php apps and scripts) don't work any more. The crashes do not always occur at the same step of the URL replay; in this respect I can not pinpoint a single script or application. However, multiple test runs repeatedly failed sooner or later. Apache has to be restarted then. Occasionally I see [apc-error] Cannot redeclare classes in the Apache error log when some wordpress blogs are accessed. The PHP error log remains empty (E_ALL), however. These happen to appear shortly before the "Bus errors", but I don't know whether there is a connection to the crash or not. My APC settings: configured with ./configure --enable-apc --enable-apc-mmap --with-apxs=... php.ini: extension="apc.so" apc.enabled=1 apc.shm_segments=1 apc.optimization=0 apc.shm_size=64 apc.ttl=7600 apc.user_ttl=3600 apc.gc_ttl=3600 apc.num_files_hint=1500 apc.user_entries_hint=100 apc.mmap_file_mask=/mnt/ramdisk/apc13.XXXXXX apc.enable_cli=0 ;apc.cache_by_default=Off apc.filters="-/some/useless/path/" ; DEPRECATED now write_lock apc.slam_defense=20 apc.file_update_protection=5 apc.max_file_size=1M apc.stat=1 apc.write_lock=1 The user cache is not used at all.
