Yum Couldn't Fork Cannot Allocate Memory I’ve been doing some awesome things to a new VM for work, namely installing CouchDB, Apache and running Node.JS apps along side a WordPress plugin using Angular.JS. It’s pretty cool. But computer’s are dicks so when it came down to installing Monit to ensure everything was lovely I got the following error: Couldn’t fork %pre(monit-5.5-1.el6.rf.x86_64): Cannot allocate memory. Bum.

error: Couldn’t fork %pre(monit-5.5-1.el6.rf.x86_64): Cannot allocate memory

Seem’s simple enough, for whatever reason Yum cannot allocate memory, so lets take a peak

Man there’s totally enough memory there, 187MB of RAM is free, Quake took less than that and is way more complicated than some stupid RPMs.. maybe it’s something else!

Quite often this error is caused because the RPM database has duplicates or got corrupted in some way, so lets try and clean that up.

Well no duplicates and the RPM database is all cool, so lets try again ..

Man, haters gonna hate!

Solving error: Couldn’t fork %pre(monit-5.5-1.el6.rf.x86_64): Cannot allocate memory

Ok, lets step back a minute and assume the error is legit, lets turn some stuff off ..

And try again!
