<p>Getting panic in http-client-request.c: line 1240 during indexing</p>
<p>I'm testing the install/setup of dovecot on an Ubuntu Focal 20.04 system, using the dovecot repo. The packages that are installed are</p>
<p>harryb@dove1:~$ dpkg -l dovecot\* solr\* jetty\* tesser\* | fgrep ii<br />ii dovecot-core 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - core files<br />ii dovecot-imapd 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - IMAP daemon<br />ii dovecot-lmtpd 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - LMTP server<br />ii dovecot-managesieved 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - ManageSieve server<br />ii dovecot-mysql 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - MySQL support<br />ii dovecot-sieve 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - Sieve filters support<br />ii dovecot-solr 2:2.3.13-2+ubuntu20.04 amd64 secure POP3/IMAP server - Solr support<br />ii jetty9 9.4.26-1 all Java servlet engine and webserver<br />ii solr-common 3.6.2+dfsg-22 all Enterprise search server based on Lucene3 - common files<br />ii solr-jetty 3.6.2+dfsg-22 all Enterprise search server based on Lucene3 - Jetty integration<br />ii tesseract-ocr 4.1.1-2build2 amd64 Tesseract command line OCR tool<br />ii tesseract-ocr-eng 1:4.00~git30-7274cfa-1 all tesseract-ocr language files for English<br />ii tesseract-ocr-osd 1:4.00~git30-7274cfa-1 all tesseract-ocr language files for script and orientation</p>
<p>Apache Tika v1.25 is also installed</p>
<p>harryb@dove1:~$ l /usr/local/bin/tika*<br />-rw-r--r-- 1 root root 79337717 Feb 3 12:40 /usr/local/bin/tika-server-1.25.jar</p>
<p>and running pretty standard-ish</p>
<p>/usr/bin/java -jar /usr/local/bin/tika-server-1.25.jar --port 9998 --host localhost -enableUnsecureFeatures -enableFileUrl --log info</p>
<p>I use mbsync to pull in sample mailboxes for testing</p>
<p>The solr conf in /etc/dovecot/conf.d/ is as follows<br />plugin {<br /> fts = solr<br /> fts_solr = url=http://localhost:8693/solr/<br /> fts_autoindex = yes<br /> fts_filters = lowercase snowball stopwords<br /> fts_tokenizers = generic email-address<br /> fts_tokenizer_generic = algorithm=simple<br /> fts_autoindex_exclude = \Junk<br /> fts_autoindex_exclude2 = \Trash<br /> fts_autoindex_exclude3 = \Spam<br />}<br />plugin {<br /> fts_tika = http://localhost:9998/tika/<br />}</p>
<p>Unfortunately indexing is panic'ing. Whether I index a test folder manually, or just looking in /var/log/dovecot.log</p>
<p>I'll see the following very consistently :</p>
<p>harryb@dove1:~$ sudo doveadm -D index -u harryb@example.com Receipts</p>
