well, the only thing that cause this issue is allowing remote access to the pcscf db with full privileges to root 
disabling remote access let everything go well without dropping 

however, i did the same on every kamailio node and didn't face this issue.

Hello Ammar,

 

this is indeed strange. There is no drop implementation in the DB API, if this happened triggered from Kamailio I could only think on a strange bug or maybe a security issue like SQL injection or similar.

 

Have you investigated in the mean time a bit more?
