Since the rollout of iOS5, we are experiencing huge sync.log file sizes (about 20 times the size before iOS 5). The server load is also constantly high, especially mysqld is very active.
Is anyone else experiencing this? We are on ZCS 6.0.10 NE.
You should check your sync.log file to avoid it filling all disk space. One file (and there are 7 of them alltogether in rotation) can easily get bigger than 50GB!
I have filed a bugzilla entry, feel free to vote on it: Bug 65879 – Since iOS 5 sync.log grows to dozens of GBs per day
