Dear all, I´m running Squid on a FC3 SMP, and the server is a Proliant 5500 multiprocessor. Recently, my squid is terminating abnormally with the following error: FATAL: xstrdup: tried to dup a NULL pointer! Squid Cache (Version 2.5.STABLE6): Terminated abnormally. CPU Usage: 55.150 seconds = 27.885 user + 27.265 sys Maximum Resident Size: 0 KB Page faults with physical i/o: 0 Memory usage for squid via mallinfo(): total space in arena: 76864 KB Ordinary blocks: 75991 KB 391 blks Small blocks: 0 KB 1 blks Holding blocks: 4324 KB 3 blks Free Small blocks: 0 KB Free Ordinary blocks: 872 KB Total in use: 80315 KB 104% Total free: 873 KB 1% I read in the mail list that maybe is a bug, but don´t know if the bug was fixed on the STABLE 9 version or if is another way to fix it. Why until these last days Squid doesn´t fail? It is running on a production enviroment since 3 months ago. Thanks to all and sorry about my english! Regards. Fernando Sclavo.-
