The problem is that ppp connection constantly hangups under load (downloadi= ng)=20 (it works perfectly with 30 kernel). syslog: pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Reply received. pptp[1942]: anon log[logecho:pptp_ctrl.c:677]: Echo Request received. pptp[1942]: anon log[ctrlp_rep:pptp_ctrl.c:251]: Sent control packet type i= s 6 'Echo-Reply'=20 pppd[1929]: No response to 4 echo-requests pppd[1929]: Serial link appears to be disconnected. pppd[1929]: Connect time 8.5 minutes. In average it works ~10 minutes.=20 I did "strace -ff -F -tt -s 200 -o ... pon ..." which produced 11MiB and 46= files (it'll take some time to dig). Do you have any ability to test ppp under load?
