[asterisk-bugs] [JIRA] (ASTERISK-26177) func_odbc: Database handle is kept when it should be released

[Joshua Colp (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-26177?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=231345#comment-231345 ] 

Joshua Colp commented on ASTERISK-26177:
----------------------------------------

Current res_odbc doesn't connect/disconnect, it maintains a pool of active connections. By default it's set to previous behavior, which is 1 connection. Due to the implementation of both res_odbc and func_odbc the combination of the defaults causes the deadlock.

> When processing normal dialplan commands, including several ODBC commands, at some point, just running a simple command like "FollowMe" locks up asterisk. Running the FollowMe command with the same parameter, but without running anything before, produces no lock. The same dialplan run under asterisk 13.2.0 produces no issues.
