This is too low for ActiveSync use. You need it to be AT LEAST as long
as the maximum heartbeat interval any of your clients might use. The
maximum for ActiveSync is something like 59 minutes. Though this is a
separate issue to the high CPU load.

This line is setting the maximum heartbeat to 2700 seconds == 45
minutes. You should have your max_execution be AT LEAST this long,
preferably a bit longer since it's possible for the actual connection
to need longer if changes are found at the very end of the heartbeat.

This is harmless and has already been fixed in Git.

This is related to a date field in some Microsoft TNEF attachment in
one of the emails being synchronized. Impossible to say what the
actual issue is without access to the attachment causing the error.
