Here are some values, but they should be adjusted for your machine: net.core.rmem_max=16777216 net.core.wmem_max=16777216 net.ipv4.tcp_rmem=4096 87380 16777216 net.ipv4.tcp_wmem=4096 65536 16777216 net.ipv4.udp_mem=16777216 16777216 16777216 net.ipv4.udp_rmem_min=16777216 net.ipv4.udp_wmem_min=16777216 net.core.netdev_max_backlog = 50000 kernel.shmall = 2097152 kernel.shmmax = 2147483648 kernel.shmmni = 4096 kernel.sem = 250 32000 100 128 Cheers, Dragos On 16/08/2016 18:26, Jack Stevens wrote: > Hi Dan, > > > > We have checked all of that and we also not using pike its really strange > > * * > > > > *From:*sr-users [mailto:sr-users-boun...@lists.sip-router.org] *On > Behalf Of *Daniel Grotti > *Sent:* 16 August 2016 17:24 > *To:* sr-users@lists.sip-router.org > *Subject:* Re: [SR-Users] Stress Testing > > > > Hi, > a couple of suggestions: > > you may running out of RTP ports. > kamailio may start to block requests if you are using pike module. > UAC may start to de-register after a short expires time, so they won't > be reachable anymore if they do not refresh their registration. > You may check your natping interval, if you have it enable.
