NAME Catalyst::Plugin::AutoRestart - Catalyst plugin to restart server processes when specified memory threshold is reached SYNOPSIS use Catalyst qw/AutoRestart/; __PACKAGE__->config->{Plugin::AutoRestart} = { active => '1', check_each => '20', max_bits => 576716800, min_handled_requests => '150', size_field => 'size', # or any other field supported by # Proc::ProcessTable::Process restart => 'exit', # alternative is kill for a more graceful restart } active 1 check_each 20 max_bits 576716800 min_handled_requests 150 restart exit DESCRIPTION Catalyst plugin to force the application to restart server processes when they reach a configurable memory threshold. Memory checks are performed every 'N' requests. This is intended as a band-aid to deal with problems like memory leaks; it's here to buy you time to find and solve the underlying issues. CONFIGURATION active This is used to turn the plugin on and off check_each This is the number of requests to wait between checks min_handled_requests Minimum application requests before process size check starts occurring. This is to prevent your application processes from exiting immediately in case your application is bigger than your max_bits limit. The default is 500 requests max_bits This is the size virtual memory can grow to before triggering a restart The default is 524288000 bits (500 mb) size_field Which size field to measure. Defaults to "size". Other values are anything that Proc::ProcessTable::Process has an accessor for, which depends on your OS. Most people will want "size" (virtual memory size) or "rss" (resident set size) SEE ALSO For trying to solve memory leaks see Devel::Leak::Object EXTENDED METHODS The following methods are extended from the main Catalyst application class. setup Create sane defaults handle_request Count each handled request and when a threshold is met, restart. _debug_process_table Send to the log the full running process table and return the size of the process AUTHORS John Napiorkowski John Goulah COPYRIGHT This program is free software; you can redistribute it and/or modify it under the same terms as Perl itself.
