6.2 Memory Exhausted

After upgrading to 6.2 I began receiving 503, 524 messages and could not update posts. My ISP told me they are experiencing similar issues when upgrading from 6.1 to 6.2. Several well-known plugins use all available memory. I downgraded back to 6.1 and the issues went away. It seems 6.2 is not ready to be shipped if it causes site failures. I don’t seem to be the only one having issues. I have two sites. Both are back to 6.1.
