40 Older Java 11 releases [[contain a bug in the SSLEngine>>https://bugs.openjdk.org/browse/JDK-8241054]], which under certain circumstances can lead to dead loops when calling URLs via SSL, resulting in high CPU usage. This bug has been officially fixed in Java 11 release 11.0.8. Therefore it is not recommended to use Java 11 releases up to and including 11.0.7.

50 === Browser (administration interface) ===
51
52 These requirements are for the administration interface of {{formcycle/}}, not for opening and filling out forms. We recommend you use a recent version of one of the following browsers. Also, please keep in mind that older browsers may have security-related bugs.
53
54 * Microsoft Edge
55 * Mozilla Firefox (recommended)
56 * Google Chrome
57
58 Internet Explorer and previous versions of Edge are not supported anymore for the backend. Using them may lead to {{smallcaps}}Ui{{/smallcaps}} glitches or other bugs.

60 == Hardware ==
61
62 Hardware requirements may differ depending on how {{formcycle/}} is used, such as how many forms have to be processed each day.
63
64 Consider the following requirement on the system:
65
66 * 1 client
67 * 40 forms
68 * 1000 form submissions daily
69 * 1000 state transitions daily
70 * 500 files created by action, eg PDF or Word files
71 * 10 simultaneously registered users in the backend
72
73 This will require the following hardware and operating system:
74
75 * Windows 2012 R2 (or newer) or Linux (64-bit)
76 * 2 x QuadCore processors @ 2,8 GHz
77 * 8 GB RAM (4 GB for the application server)
78 * 10 GB disc space for {{formcycle/}}
