WebdnaMonitor utilizes a = file that contains the process ID of the running engine

When WebCatalog is started with = the -m argument, it does not create the WebCatalog.pid file. Instead the = WebDNAMonitor creates it, and puts its own PID in it:

# cat /usr/lib/cgi-bin/WebCatalogEngine/WebCatalog.pid

root =     15568  0.0  0.0   4288 =   608 pts/17   S    12:28 =   0:00 /usr/lib/cgi-bin//WebCatalogEngine/WebDNAMonitor

The bug is that the WebCatalog.pid file is = deleted by WebCatalog on a clean exit regardless of whether or not it = created it. It should not do this if -m was passed.


if the = running engine is killed (i.e. Not usually the best way to stop any = application)

This is how = WebCatalogCtl and WebDNAMonitor stop WebCatalog. It sends it a INT = signal, which goes through the same handler as TERM so there is no = difference.

What you want to avoid is = sending SIGKILL (aka signal 9), that is closest to force-quitting an = application from the OSX GUI. The application isn't able to run any = signal handlers and do a graceful shutdown, as signal 9 cannot be = caught.

"killall" will send a TERM signal = by default, which WebCatalog will catch and use to gracefully shutdown = by running CleanExit(0).


there will likely end up = being a mismatch between the monitor and the engine. Then what will = happen is rogue instances of the engine.

Yeah you are right. Since WebCatalog deletes the = WebCatalog.pid file when it exits, the WebCatalogCtl script stops = working.
