Thanks Chris. I appreciate your help.
All 4 tomcats are on diff machines. One on each, with same tomcat version, same java version and same OS for all. Tomcats are not in cluster.

Latest 1.7 build is 1.7.0_80 release nearly 3 years ago. Note that Java 7 is no longer supported unless you have a long-term support contract with Oracle, in which case the latest version is 1.7.0_131, released earlier this month. > OS used > > > Red Hat Enterprise Linux Server release 6.3 (Santiago) Ouch! 5 years old! > # # A fatal error has been detected by the Java Runtime > Environment: # # SIGSEGV (0xb) at pc=0x00007fed24ecfe9e, > pid=21352, tid=140656275650304 # # JRE version: 7.0_21-b11 # Java > VM: Java HotSpot(TM) 64-Bit Server VM (23.21-b01 mixed mode > linux-amd64 compressed oops) # Problematic frame: # J > org.apache.http.impl.cookie.BestMatchSpec.formatCookies(Ljava/util/Lis t;)Ljava/util/List; > > # > # Failed to write core dump.

Given that the OS if 5 years old, I'm guessing the hardware is at least that old. I'd expect 5-year old hardware to be fairly trustworthy, but it may not have been properly-tested before going into production. If it's all on a single piece of hardware (all 4 Tomcats), I'd blame the hardware and look for a speedy replacement (properly-tested this time). If it was on different machines, I'd suspect a JVM bug. - -chris -----BEGIN PGP SIGNATURE----- Comment: GPGTools - http://gpgtools.org Comment: Using GnuPG with Thunderbird - http://www.enigmail.net/ iQIcBAEBCAAGBQJYilqXAAoJEBzwKT+lPKRYk8gQAJxyGn+KWUb6V0fzWdiF0gzi xh5p9tjmszS7ixEkMNZmkJH5cwWL8SjrXy0bO3s/50bfzEAOIKnqii+AEBWvKSsw W/zmh/OFJzONOPhSWFvzkI1q9pND+gwRqyIVIkHYMs/l0Vi8GeqoWwJHjaIfSRtG ZW9mDg1cH6p8/QrEynTU/B9XzNxKwIxg7YdUu97/uYPXVICDoRyF6Z8y+ISPMSpF 6OT36NDpdQXTL3xWnYM9149HE37dXjAiz1T+ms0FvP4UKLWN8hy58OdUnjW9EQpj 5IpsruGyRKsAKZzUfwWS68t4d2pq8/QUSvi+t23ZVnOkvdUy99thJ+rIUigb2942 NN6mMzpexOxkq36S7DyJrfXUVWdseeoYgEBFz+9mso2TaTf+9RD4JgLIPXjJ2LZp CvUuHZ1G45uP62qgEsek4LQdPQ8urOzPuDvW578JleRXxE0w80eNPlnFfjb5mFmz TrjGMWZE9ErnfFu6WB0ef5aNpGC5vh3TMXvT5NCVZvqRz/cBP4cXape0CZZdxxkf /lfXqOWb0fBGrzS6BoeI44nyL+Nyqei9UZDl8RZaWjah1aGE9bGYSuvvhWXhgorb Fs/4yvllgIpjRx9gDVcreE0oUFtPYh+FWLSEBYETjEFZCIZVsAGUNNDKa4kDDtXK pxsK5m9udi1kAN+sqBzC =lACD -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org ::DISCLAIMER:: ________________________________________________________________________________________________________________ Confidentiality Notice from Dixons Carphone plc (registered in England & Wales No.07105905) of 1 Portal Way, London, W3 6RS ("Dixons Carphone").
