Earlier kernels (at least linux-2.6.14-rc4) did not show this with the exactly same settings. How it happens: - open up the ppp connection over ssh. - stress it a bit with samba - after a few minutes, pinging the remote end gives ping: sendmsg: No buffer space available and I have to re-establish the connection The ssh connection seems solid afaict. Also, with bare ssh connetion, no problems occur even under load. The ppp connection seems prone to hang especially with SMB traffic (don't know why.) In dmesg, there seems to be nothing relevant. /proc/slabinfo doesn't seem to to have anything alerting in it. The underlying connection is ADSL (8/1Mbit). The driver is eepro100. ppp is ppp-2.4.3-6.2.1. ppp_deflate is in use: ppp_deflate 5536 3 zlib_deflate 18360 1 ppp_deflate bsd_comp 5312 0 ppp_async 9664 2 crc_ccitt 1952 1 ppp_async ppp_generic 20468 11 ppp_deflate,bsd_comp,ppp_async
