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 http://www.gossamer-threads.com/lists/apache/users/435414 replayed them on the test server, 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 https://bugs.php.net/bug.php?id=57581 usage is not more than 50% of the 64 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.st

I only happens when I add exit signal bus 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.
