I've seen this error a few times when running on branches wt-7833-ctw2 and wt-7833-concurrent-tiered-writers. (These branches address, in two different ways, some known issues with running longer tiered tests). The error is at the end of __tiered_server, in its err: label, so we don't know exactly the root of the error. Here's the backtrace:
(gdb) bt

Here's how I trigger the error. It usually takes a few dozen or so iterations to hit problem:
builddir=`pwd`/buildcd build/test/csuite/tiered_abort || exit 1 i=0 nruns=500 while [ "$i" != $nruns ]; do echo echo '=========================' echo Iteration "$i" ./test_tiered_abort -b ~/wt/git/wt-7833-concurrent-tiered-writers/build -h ./TEST_DIR || exit 1 ./test_tiered_abort -b ~/wt/git/wt-7833-concurrent-tiered-writers/build -h ./TEST_DIR -t "$i" || exit 1 i=`expr $i + 1` done
