Probably not, as the sessions eventually expire... just way later than expected. Also, the background thread would not be running anymore, which I think you would have noticed. 2. Some process has blocked the background thread. For example, a very long-running HttpSessionListener.sessionDestroyed method. I'm guessing you would have already noticed a stuck background thread, though. - -chris -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAluDPOYACgkQHPApP6U8 pFjOJw/8CGIxOEEWKd1rk28PcErF6LPvDBQLVTECO+miQt8SoJPzuwpICnX/mPut IliUdiPTSPplb7CHr1vsMfLGrVxOo1fD7xuQ22lMVFD8B23pe6WXwTreUnzJouDw pO9rV2mhjc6x1OaE29iCyFqbCNsswANdRcLrFAkAkdDc/ZlY1tw4VrnXPKG+uaQD sJP1lei0poek5ZOvMvG87JMC8Pe7veuUSKvO1c1q+NL3MAuI/XZWTaiJ7SRSj8JW m2paNQX+9/neHZZ0mOAuAjXTqllLGnThQTNCyaqqtXtqk4TftHYp5Tz9hBhXSXh3 +gEzbPMp5m5tWXCpdrXIFqqEArDgUpWpNGijgmMhE9e+eTYvEuadA+rMIeOr4IVO CI2QQCVzZ2vOqMd9Xa/ii0gyOjjZMYUf7qxLqBxZ6NxIFnXr+MJXBGVuFe5hvsdX hcAuzkTy9rt6pgAO6O+5YUD7d6KRCjg4bHP1614bcZgsPiwNT98ECJq22FhiEDFF l8zb7svG56qWFvsIkXAGVKSC5FT8NO9XFS9soMfIxZi0GVQS9z6qRbNDoKeO6gfI e9S+Rd7a/kogTODSBsoGl1pK/5DLF1uPLyE0HLHnvfFTgnvPU0hJy94xDQ9tiAA9 iCA9EaIak3nxy/7qAONpgEghkXHplk94ObGzZ3qj3TW0x7h4uMk= =3Wbc -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
