Since upgrading to 4.0.15 we've been having problems with /usr/local/cpanel/bin/safeapacherestart hanging. As a result, basic operations that require httpd.conf modifications either become very slow or will not complete. Bandwidth and stats are also unable to update. This is easily resolved by killing the safeapacherestart process but this shouldn't be occurring in the first place.
Given the timing of this problem and the lack of any cPanel updates having been applied it would seem that LiteSpeed's wrapper may be to blame in some manner.
