<div style="font-family: Verdana; font-size: 12px;">The system is a Scientific Linux.<br><br>The imapd process just tries to exec and then fails and exit, as you can see from the log.<br>This happens on any process that master tries to execv (e.g. ctl_cyrusdb,imapd and s on).<br>Reading around, looks like execv brings all the parent environment, but not LD_LIBRARY_PATH,<br>for some security reason....<br><br>In my case, to be sure that my daemons always run my own versions of the libraries, I just<br>compiled BerkeleyDB from sources, into my /sonicle/lib.<br>Then I compiled cyrus against it.<br>Problem is, if I bring my prebuilt package into another system, and this system has different<br>versions of my libraries into /usr/lib, execv calls will link into the system ones, not mine...<br>There must be a way to have everything link into my environement... :(<br><div><br><font size="1"> -= Mail sent through WebTop2 =-</font>
