On several occasions I have seen the apcsmart process runaway using 100% CPU while filling my syslog partition by logging the following syslog entries at an incredible rate. I have seen up to 21,800 log entries PER SECOND of the following nature:
--[snip]-- Jun 25 10:06:38 servername apcsmart[4012]: Communications with UPS lost: Communications with UPS lost - check cabling Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error Jun 25 10:06:38 servername apcsmart[4012]: smartmode: ser_send_char failed: Input/output error --[snip]-- There is nothing wrong with the cabling, and nut runs fine until this begins. If I kill apcsmart and then restart the nut ups driver everything goes back to normal for days or weeks or months at a time. I am using nut v2.4.1-r1 on a Gentoo Linux system with a 2.6.27 kernel on an AMD Athlon X2 64bit dual core system. Any thoughts? What other information can I provide to help diagnose and hopefully solve this issue?
