@ankurshrivastav reported that the CPU usage is at 100% on the server hosting sendy (the mass emailer being used by AAP)

Logged in to the server did a basic top sorted by CPU usage .. and this revealed 2 PHP processes eating up a lot of resources.

to figure out what was particularly being done by this php process.. did a basic ps ax | grep php this showed that the php script that was sending out the mails on scheduled cron that was stuck and taking up all the CPU as shown below

I logged in and looked around inside sendy.. in the database.. but could not locate where the script was stuck or why.. since the script runs every 5 mins over cron.. it was safe to kill it.. which is exactly what solved the issue..
