Rippled Validator server state hangs on connected, will not propose

[TaylorWarden]

My rippled validator seems to be stuck in the connected state and will not propose after purging ledgers on the server (it was becoming full). 

Any suggestions as to why this is happening?

I'm not aware of a "purging" operation, maybe something broke. There's not enough info in this post to help you any further than that, sorry.
