Major Description
I'm writing a ssl hook to look up a cert from mysql database.
the SNI Hook stall at fetch cert from mysql database due to a database dump lock every mid night.
the SSL Client got timeout and closing the connection before SNI Hook reenable the connection.
Segmentation fault due to the TSVConnSSLConnectionGet() can not get a SSLVC during reenable the SSLVC.
