<br></div>Is there any other way I can initialize a hash with values from a database table not explicitly designed for use with htable module? (The other way I could solve my problem would be if I could use the is_domain_local() from the domain module also in the onreply_route.)<br>
<br></div><div>Thanks, Hugh, for pointing out the crash. I found a couple of core files from my test on my file system, too. I didn't see the "core was generated" message in the log, so I didn't think there was one there.<br>

Indeed, the db connection is not initialized at the time of
executing event_route[htable:mod-init]. This is executed after all
modules are initialized, but the sqlops connections are initialized
in child init.<br>
<br>
However, it should not cause this crash. What version are you using?
Because latest master and 4.1 have a simple condition at
sql_api.c:257.<br>
