Relevant specs: FreeBSD 3.1-STABLE US Robotics Sportster 56K external 486/133 sio0 port speed: 115200 After about a week of continuous online operation with user mode ppp, FreeBSD began reporting silo overflow messages. I had been downloading significant amounts of data prior to these messages with no problem. No changes have occurred to this machine since early March. After several boots and reconnections, the silo overflow messages persisted and got worse. I shut the modem off and left it alone for a bit. When I returned about an hour later, the messages stopped. Several hours later they began appearing again. Due to prior experiences with USR modems I suspected a heat problem with the modem. I shut it off, pointed a small desk fan at the device and waited a bit. About 10 minutes later, the modem functioned with no silo overflows. My question is; could a heat problem with an external modem manifest itself as an silo overflow? I know diagnosing heat related problems is not an exact science, but the cause/effect/workaround of this case _seems_ pretty clear. My anecdotal experience with USR and heat problems tends to reinforce my guess. I'm more concerned with avoiding these sort of problems than saving money; what brands/models of external asynchronous modems would you recommend for FreeBSD? -- Allen Campbell | Lurking at the bottom of the allenc@verinet.com | gravity well, getting old.
