I am getting a recurring situation where the chassis stops taking calls and gives a fast busy signal. I have reported this issue to commworks' technical support but the technician said that since I was running a chassis with more than 5 PRI with dual 70amps, they could not guarantee anything. I would need to use 130Amps and he swiftly emailed me the 3com info bulletin about power consumption on the chassis ... I am hoping someone on the list could help me: The problem affects mostly the chassis that receives most calls (i.e. the one at the begining of the call queue). It used to happen once in a while but it now happens daily. Inventory: A chassis with dual 70amps, 1hiper arc(5.1.99-8 128Megs), 11 DSP's(2.1.9 PRI 5ESS) the Arc is running ospf and using an IP pool of 260 IP's Symptoms: I checked the syslog files and noticed that at the time of the incident, the Harc sends the following logs: ** Message: At 09:33:42, Facility "IP", Level "CRITICAL":: Deleting IGMP network before finally freeing dynamic network IPpdb ** Message: At 09:34:18, Facility "IP", Level "CRITICAL":: Deleting IGMP network before finally freeing dynamic network IPpdb [...] (Previous message was repeated 10 times) ** Message: At 09:38:48, Facility "IP", Level "CRITICAL":: ip_fwd_get_opt: no IP address available for dynamic address assignment ** Message: At 09:38:48, Facility "IP", Level "CRITICAL":: Deleting IGMP network before finally freeing dynamic network IPpdb ** Message: At 09:39:04, Facility "IP", Level "CRITICAL":: ip_fwd_get_opt: no IP address available for dynamic address assignment [..] (Previous message was repeated several times) I then noticed that an OSPF cisco neigbor complained that the interface on the HARC went down: ** Message: 85194: May 18 13:42:23.095: %OSPF-5-ADJCHG: Process 1, Nbr xxx.xxx.xxx.xxx on FastEthernet0/1 from FULL to DOWN, Neighbor Down: Dead timer expired At this point, all dialup customers have been disconnected from the DSP's on the chassis And I see the following syslog message from HiperArc: ** Message: At 09:43:23, Facility "Configurator", Level "INFORMATION":: HiPer system configuration complete at 5/18/2001 09:43:23 Doing a "show board crash" shows that a crash happened at 5/18/2001 09:41:43 ============================ - I don't think this is related to the number of cards in the chassis because I've seen this happen with another chassis loaded with 7 DSPs - I've tried several HARC codes. All 5.x.xx crash - The DSP's show LocalOutOfService or RemoteOutOfService on most of the PRI channels. The only way to restore them is to reboot the DSP.
