Confirmed fixed in .12 insofar as the CPU load is now alleviated. Search results aren't coming back as expected though - will test some more and raise separate defect...

And; Upgraded to AS 2.0.11 and IMAP 2.4.0 earlier today - made no difference.

Should also point out ; I use Dovecot for IMAP Once Apache uses 100% no syscalls occur according to strace

Running Apache 2.2.23 with PHP 5.3, ActiveSync 2.0.10 and the other latest Horde components. I have seen Apache take 100% CPU on my single CPU server running ActiveSync a few times in the last few weeks post upgrading to Horde5. Today I noticed that when I performed a search on an email folder from an iPad using the 'Search on Server' option from the iPad Apache immediately went nuts. Restarting Apache clears the issue, leaving it doesn't seem to improve anything and the process keeps taking large amounts of CPU. Happy to provide further logs - I had a look through the Apache logs and didn't see anything remarkable, haven't had time to dig deep yet but raising so it can be reviewed.
