Hi Volker,<br><br>I forward your request to the user list since I don't currently have much time to process it.<br>quickly testing 2.4.1, I wasn't able to reproduce it.<br><br>a question: was it working with the exact same context/config with 2.2.2?<br>

Hello,<br>
<br>
i'm the developer and project leader of FreeNAS which uses NUT UPS. During upgrading from 2.2.2 to 2.4 i realized that i get a core dump in upssched when an event occurs. During my research i found out that this happens when the line:<br>
<br>
AT ONBATT * START-TIMER shutdown 30<br>
<br>
is parsed. It crashed then in add_arg_word at the following line:<br>
<br>
ctx->arglist[argpos] = realloc(ctx->arglist[argpos], newlen);<br>
<br>
I looked at the code (and did a diff to the previous stable code) but did not find anything. I'm at the end of my knowledge now, so i want to ask you if you did have any idea?<br>
<br>
Regards<br>
Volker Theile<br>
<br>
The output of some variables before the crash:<br>
<br>
argpos: 5<br>
ctx->numargs: 6<br>
ctx->maxargs: 5<br>
ctx->wordbuf: 30<br>
wbuflen: 2<br>
ctx->argsize[argpos]: 0<br>
ctx->arglist[argpos]: 0<br>
newlen: 3<br>
