This issue can lead the machine being stuck on high network load, by double freeing an inp, you can corrupt/leak an inp lock, and the network stack can wait definitely on this inp lock to be released. You get this assert only with INVARIANTS defined. Of usual, we can have more than one issue here, but this INP_TIMEWAI|INP_DROPPED issue need to be fixed anyway. -- Julien --UNWhH0cTeRXX8arXRVpufSMpxKxBxOBi8-- --hpo3idiVRA9C8RP2Uug5lNLsNiiLQ1soo Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJX9gKZAAoJEKVlQ5Je6dhxT8sIALTO7JPbleGxCy9w0a6sRMkN xugGeEmPA2RLPduj4WbDHANRvXCx+tNEjdlkeHPd3m1M4Vh7Bs5aGr42QG/ZdiW3 HIP9nOwh3xSSyA5m+CVC/lqQoR7r3xX+9W9D1mfRCWK3O2NcubsxhqZOecgP3uAY /chrvU5zCd/Kkeep3TNhlX39PLf4Vi46tMCmfwV2JW7UKOgVWm3w1Bb3fXcfea2e +gnlEFTeng0pRtOd/emQwOcIWIC2I80HDurSXX3O3zkUCC4eQX0bMmX1vvFwSUHa zqRmBLBH3k7/AKqKBNy7b19lwzlO6eeJfYUaKmP1afXTx54wY5Z8ABVwvdP/iKQ= =TLuh -----END PGP SIGNATURE----- --hpo3idiVRA9C8RP2Uug5lNLsNiiLQ1soo--
