(again me)
Found some addtional time in the last weekend, so here some more ideas about the problem:
Because Iam new in (open)vpn, it could be that all my trouble comes because of an configuration mistake, but Iam getting more an more sure, that the crash comes because of openvpn makes to large packages which causing the skput-error.
(But the reason also could be another one, Iam not familiar with analysing the output of openvpn).
But for me its seems, that the the segmentation fault occurs after opevpn recieves and decrypted the data at the point where it send the data to the tun-interface or directly after that (see also below "last lines of openvpn-output...").
I allready tried some options like (tun-mtu 1500,mssfix 1400, fragment 1400).
What wonders me a bit is that the mtu-test never comes to an end (I ran it over night for more than 8 hours, and it did not stop (I just see a lot of R and W)).
Because of dmesg I thought, maybe the packets are to big and tried much smaller options (tun-mtu 600,mssfix 500, fragment 500, but still the segmentation fault, only wiht an smaller value:
... skput:over: c2829350:0 put:600 dev:<NULL> ...
But keep in mind that Iam newbie and maybe all the ideas are bullshit.
