Tried to get e backtrace after recompile but I did not succeed,
whatever I tried.
Then I hypothesized wpa_supplicant could be stopped by some different
process. I started fiddeling with whereami and ifplugd.
Deinstalling whereami did not solve my problem so I modified the
configuration of ifplugd which was
,----[ /etc/default/ifplugd ]--
| INTERFACES="all"
| HOTPLUG_INTERFACES="all"
|
| ARGS="-q -f -u0 -d10 -w -I"
| SUSPEND_ACTION="stop"
`----
Now it is
,----[ /etc/default/ifplugd ]--
| INTERFACES="eth0 eth1"
| HOTPLUG_INTERFACES="eth0"
|
| ARGS="-q -f -u0 -d10 -w -I"
| SUSPEND_ACTION="stop"
`----
where eth0 is my (wired) ethernet and eth1 the Intel Wireless LAN
Adapter.
I did not test the ethernet but WLAN runs fine for nearly 24 hours
without wpa_supplicant disappearing somehow. I will test this setting
longer ...
Actually, I believe, the problem I reported is not a bug of
wpa_supplicant, but a bad interaction of wpa_supplicant and ifplugd
causing wpa_supplicant to be killed during bad WLAN connecticity.
If others can reproduce this behaviour it may be useful to add this to
the package's documentation.
So long & thanks a *lot*
Sebastian
