Creating client/server ssl profile LTM 11.4 reports Error Reading cert PEM file [path] for profile [profile]: memory exhausted

I'm seeing this isse on one of my BigIPs (test/dev environment) but not the other. I've attempted to sync them more than once but to no avail. On the affected machine, I've tried more than one cert as well but to same result. I also tried going in through an SSH session but it reports "File object by name ([certname]) is missing. I've also tried deleting and re-creating the certs. Any help at this point would be greatly appreciated. Thanks!
