After applying 10.7 Hotfix #24 and higher, we have found out that the jetty files have moved from the /work directory  to /tmp in Linux or WindowsTemp in Windows.  An admin (Linux or Windows) may accidentally delete items from the temp directories

 

APM 10.7 HF 24 and higher.

/work folder instead of the default /tmp folder.
