并收到错误:(对于所有脚本，错误相同）
DBI connect（＆＃39; dbname = scs; host = 192.168.18.23; port = 5432＆＃39;，＆＃39; postgres＆＃39;，...）失败：致命：对不起，已经有太多客户了at /var/fdp/reportingscript/sdp_incoming_traffic_tps_report.pl第38行。
此外，如果我一次手动运行一个脚本，它不会显示任何错误。
为了您的参考，我附上了我已经显示上述错误的脚本：

请帮助，我该如何避免此错误。
先谢谢。

正确的问题，如错误消息所示，一次运行所有这些脚本需要比服务器允许的更多数据库连接。如果它们单独运行良好，那么单独运行它们就可以解决这个问题。
潜在的问题是您的crontab错误。 * 1 * * *每天将从0100到0159每分钟运行所有脚本。如果完成时间超过一分钟，那么新的集合将在上一个集合完成之前启动，这需要一组额外的数据库连接，这些连接将很快地通过可用连接池运行。
我认为您只需要每天运行一次日常脚本，而不是六十次，所以将其更改为5 1 * * *只运行一次，在0105。
如果仍然存在问题，请在不同的时间运行每个问题（无论如何这可能是一个好主意）：
5 1 * * * /var/fdp/reportingscript/an_outgoing_tps_report.pl
10 1 * * * /var/fdp/reportingscript/an_processed_rule_report.pl
15 1 * * * /var/fdp/reportingscript/sdp_incoming_traffic_tps_report.pl
20 1 * * * /var/fdp/reportingscript/en_outgoing_tps_report.pl
25 1 * * * /var/fdp/reportingscript/en_processed_rule_report.pl
30 1 * * * /var/fdp/reportingscript/rs_incoming_traffic_report.pl
35 1 * * * /var/fdp/reportingscript/an_summary_report.pl
40 1 * * * /var/fdp/reportingscript/en_summary_report.pl
45 1 * * * /var/fdp/reportingscript/user_report.pl
