This program runs for about an hour and consumes about 1Gig of memory. I was getting a lot of these errors, but they were significantly reduced when I reduced the golang memory usage. (by reducing the in memory state that I was keeping)
Any idea on how I can go about debugging this? ---------------------------------- fatal error: unexpected signal during runtime execution [signal SIGSEGV: segmentation violation code=0x1 addr=0x9 pc=0x427b64] runtime stack: runtime.throw(0x687143, 0x2a) /go/src/runtime/panic.go:605 +0x97 runtime.sigpanic() /go/src/runtime/signal_unix.go:351 +0x2bc runtime.newArenaMayUnlock(0xad3800) /go/src/runtime/mheap.go:1683 +0x34 runtime.newMarkBits(0x55, 0x55) /go/src/runtime/mheap.go:1598 +0xb5 runtime.(*mspan).sweep(0x7fd0c05133a0, 0xc420000f00, 0xc420000f00) /go/src/runtime/mgcsweep.go:311 +0x4ed runtime.sweepone(0x4355e8) /go/src/runtime/mgcsweep.go:113 +0x126 runtime.gosweepone.func1() /go/src/runtime/mgcsweep.go:137 +0x2d runtime.systemstack(0xc4204964b8) /go/src/runtime/asm_amd64.s:344 +0x72 runtime.mstart() /go/src/runtime/proc.go:1125 goroutine 3 [running]: runtime.systemstack_switch() /go/src/runtime/asm_amd64.s:298 fp=0xc42003ef70 sp=0xc42003ef68 pc=0x458730 runtime.gosweepone(0x0) /go/src/runtime/mgcsweep.go:136 +0x4c fp=0xc42003efa0 sp=0xc42003ef70 pc=0x4223cc runtime.bgsweep(0xc420070000) /go/src/runtime/mgcsweep.go:55 +0xc1 fp=0xc42003efd8 sp=0xc42003efa0 pc=0x421ee1 runtime.goexit() /go/src/runtime/asm_amd64.s:2337 +0x1 fp=0xc42003efe0 sp=0xc42003efd8 pc=0x45b351 created by runtime.gcenable /go/src/runtime/mgc.go:216 +0x5a goroutine 6 [chan receive, 9 minutes]: database/sql.(*DB).connectionOpener(0xc4200c5040) /go/src/database/sql/sql.go:871 +0x55 created by database/sql.Open /go/src/database/sql/sql.go:609 +0x1f0 goroutine 17 [running, locked to thread]: goroutine running on other thread; stack unavailable goroutine 5 [chan receive, 2 minutes]: github.com/golang/glog.(*loggingT).flushDaemon(0xad3b80) /src/github.com/golang/glog/glog.go:879 +0xa1 created by github.com/golang/glog.init.0 /src/github.com/golang/glog/glog.go:410 +0x205 -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
