Taking extremely long and sometimes breaking while trying to bulk-post

[theabhinavdas]

I'm using openlitespeed cloud image for wordpress, deployed on digitalocean.

Every time I try to post more than 15 posts at once, these messages show up on the server logs:

[435200] [95.142.160.195:38412#wordpress] No request delivery notification has been received from LSAPI application, possible dead lock.

What is a good way to bulk post?
