For Solr, there's a code path in the FTS expunge code that will silently toss
expunge requests:
if (ctx->last_indexed_uid == 0 ||
uid > ctx->last_indexed_uid + 100) {
/* don't waste time asking Solr to expunge a message that is
highly unlikely to be indexed at this time. */
return;
}
So it's possible you are running into that.
