So Linux, FreeBSD and others keep pmtu discovery for UDP turned off by default. With syslog this can be a big problem. In effect using a TCP connection keeped alive it's possible to avoid this problem. antirez -- Salvatore Sanfilippo <[EMAIL PROTECTED]> - ALICOM snc - www.alicom.com pgp key: finger [EMAIL PROTECTED] [2852F54A49653429 1D1BF6DA24C712BF] "ha conati di vomito la terra, e si stravolge il cielo con le stelle, e non c'e' modo di fuggire, e non c'e' modo di fuggire, mai."
