Why not? MANY fixes have been included in the upgrades. <br>
Improved security at the least. There are 10-15 versions between where
you are operating and what is current<br>

this been fixed in later versions?<br>
1.4.37 is current, or at least it was in the last few days.<br>
<br>
Upgrading with no reason isn't suggested, but in this case you have a
good reason, and if you dig deep enough you may find the fix is already
in place.<br>

Hello Asterisk community,<br>
<br>
We are having some problems with crashes in Asterisk, my asterisk<br>
versions are 1.4.24.1 and 1.4.23.2. I have found this:<br>
<br>
"~/work/asterisk-branch-1.4$ svn log -c 260345<br>

Fix potential crash from race condition due to accessing channel data<br>
without the channel locked.<br>
<br>
In res_musiconhold.c, there are several places where a channel's<br>
stream's existence is checked prior to calling ast_closestream on it.
The issue<br>
here is that in several cases, the channel was not locked while
checking the<br>
stream. The result was that if two threads checked the state of the
channel's<br>
stream at approximately the same time, then there could be a situation
where<br>
both threads attempt to call ast_closestream on the channel's stream.
The result<br>
here is that the refcount for the stream would go below 0, resulting in
a crash.<br>
<br>
I have added proper channel locking to res_musiconhold.c to ensure that<br>
we do not try to check chan->stream without the channel locked. A<br>
Digium customer has been using this patch for several weeks and has not<br>
had any crashes since applying the patch.<br>

How can i apply this patch on my asterisk versions: 1.4.24.1 and<br>
1.4.23.2? do i have to apply this patch manually?<br>
<br>
Thanks in advance for your help<br>
